LOUIS DILLON, OF ATTLEBOROUGH, MASSACHUSETTS, ASSIGNOR TO DAGGETT &OLAP, OF SAME PLACE.

BRACELET.

SPECIFICATION forming part of Letters Patent No. 358,339, dated February22 1887.

Appliea tion filed December 18, 1886. Serial No. 221,982.

To all whom it may concern:

Be it known that I, LoUIs W. DILLON, of Attleborough, in the county ofBristol and State of Massachusetts, have invented anew and usefulImprovement in Bracelets; and I do hereby declare that the following isajfull, clear, and exact description of the same.

My invention is an improvement in brace lets of that class in which thebracelet is composed of two Wings hinged to a central (generallyornamental) piece, ,with the free ends These bracelets, as heretoforemade, have been formed with springs of varied construction andarrangement, but all, so far as I am aware, pressing directly upon thearms or wings to hold them together, and in these bracelets the wings,when open, are resisted by the direct pressure of the spring.

My invention consists of a spring-lock for the wings of the bracelet,designed to lock the wings in a closed position, and also, if desired,to lock them in an open position.

In the accompanying drawings, Figure 1 is a plan view of the inventionwith the wings closed. Fig. 2is a perspective with the wings partlyopen. "Fig. 3 is a section through the center of the barrel.

In these drawings, A B represent the wings of the bracelet. To thehingedend of each is fixed a part of the hinge. On the part A this consists ofa tubular piece, 0, having a cap on the end I). The inner end of thistubular piece a, is serrated, as shown at 0. Inside of this is fixed a'barrel d, half inclosed in'the tube a and half projecting across thebracelet forming the hinge. The wing B' has a tubular piece, 6, fixed toits end on the side opposite that on which the piece a is fixed. Thissecond tubular piece is serrated to fit the serrations 0, and theserrations are so arranged that when they are interlocked at one pointthe bracelet is held in a closed position; atanother, the bracelet isheld in an open position, all as shown. The two tubular pieces are heldwith their serrations in contact by means of a spring, 9, located in thebarrel d, with one end attached to the cap or end of the (N0 model.)

tubular piece a, and the other extending through the end of the barreland being attached to the end of the tubular piece 6. The spring isshown as a spiral one, and when in place is under longitudinal strain,so as to hold the serrations interlocked, and the forcible opening orclosing of the bracelet causes the serrations to ride up over each otherand look into the adjoining serrations.

I do not confine myself to the particular kind of serrations shown, northe particular form of spring or hinge, the essence of the inventionlying in the interlocking serrations or points, and the purpose of theinvention would be carried out if there were only one notch and onepoint, with a spring pressing them together, adapted to hold the partsin engagement; but the construction shown, having more than onenotch,'allows the bracelet to be' locked in an open position. which isalso convenient.

I claim- 1. A bracelet composed of wings, and the hinged joint betweenlhe wings having a notch and point interlocking, held tug'f-lllel by thepressure of a spring to retain the wings in a closed position,substantially as described.

2. A bracelet composed of wings and a hinged joint between thewings,having a point and notches or serrations, and a spring adapted tohold the point in contact with the notches or serrations, whereby thewings may be retained in an open or'closed position, substantially asdescribed.

3. In combination with the wings A B, the tubular pieces a e, fixedrespectively thereto, and having their ends serrated, the barrel d, andthe spring inclosed in the barrel connecting the tubular pieces anddrawing them together, substantially as described.

In testimony whereof I have signed my name to this specification in-thepresence of two subscribing witnesses.

LOUIS W. DILLON.
